Obama’s been drawing record crowds from San Francisco to Des Moines — but there was always the question of whether he could produce a similar effect among real live voters.

He did so in a way that no one predicted. 57 percent of the caucus goers tonight had never caucused before. Most impressive: As many people under thirty showed up as senior citizens.

That’s fucking nuts is what that is. That’s the Rock the Vote political wet dream that never ever comes true… actually coming true.

What this portends for Obama as a national candidate is something truly special. He’s not only proven that he can draw the support of independents and open-minded Republicans. He’s the one guy who can make the Democratic pie higher, bringing new, unlikely voters into the fold. If he could replicate this kind of support among young people in a general election, it’s game over.
